Implementations

impl SpatialNodeIndex

pub const INVALID: SpatialNodeIndex = _

pub const UNKNOWN: SpatialNodeIndex = _

May be set on a cluster / picture during scene building if the spatial node is not known at this time. It must be set to a valid value before scene building is complete (by finalize_picture). In future, we could make this type-safe with a wrapper type to ensure we know when a spatial node index may have an unknown value.

impl SpatialNodeIndex

pub fn new(index: usize) -> Self

Trait Implementations

impl Clone for SpatialNodeIndex

fn clone(&self) -> SpatialNodeIndex

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpatialNodeIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SpatialNodeIndex

fn default() -> SpatialNodeIndex

Returns the “default value” for a type.

impl Hash for SpatialNodeIndex

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MallocSizeOf for SpatialNodeIndex

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for SpatialNodeIndex

fn eq(&self, other: &SpatialNodeIndex) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Peek for SpatialNodeIndex

unsafe fn peek_from(bytes: *const u8, output: *mut Self) -> *const u8

Deserialize from the buffer pointed to by bytes.

impl Poke for SpatialNodeIndex

fn max_size() -> usize

Return the maximum number of bytes that the serialized version of Self will occupy.

unsafe fn poke_into(&self, bytes: *mut u8) -> *mut u8

Serialize into the buffer pointed to by bytes.

impl Serialize for SpatialNodeIndex

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SpatialNodeIndex

impl Eq for SpatialNodeIndex
